Specification of Letters Patent. Patented J fine 13, 1916.

Application filed March 1, 1916. Serial No. 81,380.

To all whom it may concern:

Be it known that I, GEORGE S. MEYER, a citizen of the United States, anda resident of Newburgh, in the county of Orange and State of New York,have invented a new and Improved Horseshoe, of which the following is afull, clear, and exact description.

Among the principal objects which the present invention has in view are:to avoid the loosening of anti-slipping devices when placed in service;to provide means for automatically increasing the grip of a shoe on saiddevices; and to simplify the means for accomplishing said result.

Drcmoinga-Figure 1 is a bottom view of a shoe and auxiliary calkstherefor, said shoe being constructed and arranged in accordance withthe present invention; Fig. 2 is a front edge View of a shoe constructedand provided with calks of the character mentioned; Fig. 3 is a sectionshowing a heel fragment of the shoe and an auxiliary calk attached inservice relation thereto, the section being taken as on the line 3-3 inFig. 2; Fig. 4 is a horizontal section taken as on the line 4-4 in Fig.3; Fig. 5 is a detail view showing the side of one of the auxiliarycalks employed in the present invention.

Descriptz'0n.-As seen in the drawings, a shoe 10 having a toe clip 11,is provided with a series of turrets 12. The turrets 12 are provided tolocally increase the thickness of the shoe structure for reinforcing thesame where sockets are bored to receive the tapered shanks 18 of theauxiliary calks 14.

As seen best in Fig. 3 of the drawings, the calks 14 have a cutting edge15, a square face 16, and a strengthening web 17. The shoe has a seriesof keys 18, each extending from the inner surface of one of the socketsformed in the turrets. The keys 18 are permanently and rigidly mountedin the shoes and turrets to engage the top-opening tapered slot 19 cutin each of the shanks 18, as shown best in Fig, 5 of the drawings. Therelation of the keys 18 and slots 19 is such as to require driving thecalks to completely seat the shanks 13 in the sockets provided therefor.This operation results in each of the keys 18 spreading the shanks 13 tomore firmly grip the same in the sockets provided in the shoe andturrets 12 thereof.

Calks which are removably attached to shoes as at present constructed,are objectionable for the reason that it is found thating a series ofopen-ended sockets; a plurality of calks, each having a shank, saidshanks being each provided with a topopening slot formed in the sidethereof; and a plurality of wedge-shaped members rigidly mounted in saidsockets for engagement by said 'slots.

2. The combination of a horseshoe having a plurality of tapered sockets;a plurality of removable calks, each having a tapered shank for fittingsaid sockets; and means for expanding said shanks as the same are driveninto said sockets, said means embodying a key member permanently mountedin and extending from the inner surface of each of said sockets, and atapered slot formed in the side of each of said shanks.

3. The combination of a horseshoe having a series of open-endedupwardly-tapering sockets, and a plurality of downwardly-tapering keymembers, each of said key members extending into one of said socketsfrom the side wall thereof; and a plurality of calks, each of said calkshaving a shank tapered in correspondencewith said sockets, and each ofsaid shanks having a slot formed therein, said slots tapering inconformity with said key members to be enlarged thereby when said calksare driven into said sockets.

4. The combination of a horseshoe having a series of open-endedupwardly-tapering sockets, and a plurality of downwardly-tapering keymembers, each of said key members extending into one of said socketsfrom the side wall thereof; and a plurality of calks, each of said calkshaving a shank tapered in correspondence with said sockets, and each ofsaid shanks having a slot formed therein, said slots tapering inconformity with said key members to be enlarged thereby when said calksare driven In testimony whereof I have signed my into said sockets, saidcalks being further name to this specification in the presence of 10provided With squared faces, the edge of tWo subscribing Witnesses.

each of said faces adjacent said shoe when in service, being removedtherefrom to per- GEORGE S. MEYER. mit the insertion of a tooltherebetvveen for Witnesses:
